Metagenomic Sequencing @ CRS

Workflow

Metagenomic sequencing enables comprehensive analysis of microbial DNA isolated from mixed samples, providing insights into the diversity, functional potential, and interactions of microbial communities within a sample. Based on shotgun whole genome sequencing, the informatics approach identifies microbial fragments present in a sample, allowing for unbiased detection and characterization beyond targeted assays. Whether you are investigating bloodstream infections, monitoring microbial dynamics, or exploring host–microbe interactions, we can take your extracted DNA and generate high-quality, multiplexed libraries ready for next-generation sequencing.

These workflows are based on experiences in the Kisat lab at CPM, who recently developed a laboratory and computational workflow for metagenomic sequencing of plasma DNA and enrichment of microbial DNA fragments (Dominguez et al. Clinical Chemistry 2025, https://academic.oup.com/clinchem/article/71/5/567/8069772 and Zhang et al. medRxiv 2026, https://www.medrxiv.org/content/10.1101/2025.11.06.25339688v1).

  • Double-Stranded DNA Library Preparation
  • Single-Stranded DNA Library Preparation
  • Enrichment of microbial DNA by size selection (for plasma samples)

Potential Applications

  • Microbiome analysis in plasma and other biofluid samples
  • Pathogen detection for infectious disease
  • Microbiome analysis in tissue samples
